Problem

Jira macro cannot find a Jira project that has alphanumeric characers within its project key.

Reproducing

Jira configured to accept alphanumeric characters.
XML jira-properties.xml modified.
These are the changes.

jira.projectkey.pattern:

jira.projectkey.pattern = ([A-Z][A-Z0-9]+)

Afterwards, trusted application was applied in both sides.
Jira Issue macro was insert into confluence, however, the error was the same as this issue which says:

"The JIRA server was not able to process the search. This may indicate a problem with the syntax of this macro..."

Fix:

None

Workaround:

None
